You kinda do need to figure that out - EIA says that it takes 7.42cf of gas to make 1kWh of energy. https://www.eia.gov/tools/faqs/faq.php?id=667&t=8 https://w

Maybe I shouldn't have multiplied that by the efficiency of the plant, but rather just taken of distribution losses.

They are averaging the efficiency from the current fleet of gas turbines after subtracting the useful heat output and coming up with 44.4%. However, it’s a misleading number in multiple ways because the fleet is made up of a mix of low and high efficiency turbines. Grid operators use a mix of turbine types as a cost optimization, a far cheaper and far less efficient turbine that’s only used 1% of the time it worth it. The average number of kWh per cf of gas is therefore heavily in favor of high efficiency turbines.
